[More Info]

Wilwood’s GT Rotor and Hat Assemblies are preassembled packages of our latest and greatest technology and design. The pre-installed bolt on rotor mounting and safety wire makes a quick and easy replacement for OEM’s, Mil-Spec and NGO’s. GT rotors are built for the extreme conditions. The superior heat absorption and dissipation characteristics of these heavy wall directional vane rotors are the keys to preventing heat fade and realizing long service life from the rotors and pads. All rotors are cast from premium grade, long grain carbon iron for long wear, thermal stability, and resistance to distortion. Assembled with aluminum alloy rotor hats, high grade fasteners and safety wire.
